[origin: US2015246684A1] A system and method of controlling a scissors lift vehicle are provided. The scissors lift vehicle system includes a carriage including a plurality of independently steerable wheel assemblies configured to engage a travel surface. The plurality of independently steerable wheel assemblies, each steerable about a steer axis of rotation include one of the plurality of wheel assemblies being designated a master wheel and the remaining wheel assemblies being designated slave wheels. The wheel assemblies each include a variable-speed steer actuator configured to rotate a respective wheel assembly about the steer axis of rotation of that wheel assembly at a selectable rate. The wheel assemblies each also include a wheel including a respective drive axis of rotation and a variable-speed drive actuator configured to rotate that wheel about a respective steer axis of rotation at a selectable rate.
